Three-dimensional reconstruction of flagella from the wild type and a mutant. Surface rendering representations of the wild type (A) and oda1 (B) flagellum seen from a different angle compared with Fig. 1. Six of eight dynein heavy chains form three dyads in the inner dynein arm. (left) The proximal end. (right) The distal end. Two radial spokes (red arrowheads) and one protrusion (red arrows) are associated with the three dyads, respectively. Stereo pairs are shown in Fig. S1 (available). Online supplemental videos are also available. (C) Fourier shell correlation curve of the oda1 mutant.
